Automated selection of test cases for regression testing

ABSTRACT

Systems, methods and computer program products for performing software regression testing are provided. A sitemap comprising a hierarchy of nodes is displayed on a display, each node representing a block of source code for a program. An indication of a user selection of a plurality of nodes in the hierarchy is received. Responsive to receiving the indication, a lowest node of the nodes that is located at a lowest level of the hierarchy is determined and identified as a user selected node. A list of test cases to test the source code represented by the user selected node is displayed. Responsive to receiving an indication of a selection of one of the test cases in the list of test cases displayed, a message having an indication to execute the one of the test cases in the list of test cases displayed is transmitted, to a server device via a network.

FIELD

Some embodiments described herein relate to software testing, and in particular to regression testing of software.

BACKGROUND

Various commercial and open-source tools exist to assist with the automation of test cases for software testing. The automation of test cases requires developing a comprehensive approach to test all of the functional areas that the software is deployed on. This may involve test cases invoked to fully test software applications. For example, one test case may be required to test a functional area such as a website user interface, whereas a separate test case may be required to automate CLI test case scenarios used in connection with the website. Likewise, if a user wants to implement testing of a Java application and a web service running components of this Java application, the user may build separate components to consume each of the Java application and the web service.

Once suitable test cases have been designed and selected, testing systems can execute the test cases using the application under test and verify the performance of the application under test.

Typically, software components are continually updated by their authors to provide new functionality, fix bugs, ensure interoperability with new versions of other software or operating systems, etc. It is desirable to test updated software components before the revisions are released to users.

Such testing, referred to as regression testing, is designed to identify if any new software bugs, or regressions, have been introduced into an application after the application has been changed. Regression testing may be further designed to determine whether a change in one part of the application has affected other parts of the application, which is a common occurrence.

Regression testing typically involves re-running the original test cases that were performed when the application was initially developed and checking to see whether any new faults have been introduced or previously fixed faults have re-emerged. It may not be necessary to execute all of the test cases against the application under test during regression testing, as not all of the test cases may invoke the changed source code. Thus, a large part of regression testing includes systematically selecting an appropriate set of tests needed to adequately cover a particular change.

Selecting regression tests based on changed portions of source code is time-consuming and error-prone as the user needs to go through the test case categories, test cases, etc., and review and select required regression tests. Thus, a user may still not be confident whether any required test has been selected or has been missed.

Some embodiments described herein provide systems or methods for selecting and executing test cases for use in regression testing of software. According to some embodiments, a hierarchy of nodes is displayed on a display of a device where each node of the hierarchy of nodes represents a block of source code for a program. Responsive to a user selection of a plurality of nodes, a lowest node in the plurality of the nodes that is located at a lowest level of the hierarchy of the nodes is determined and identified as a user selected node. Responsive to a user selection of a test case from the list of test cases displayed, a message is sent to a server device to execute the test case.

FIG. 1 is a block diagram illustrating a client-server system for the testing of software programs according to an embodiment. As shown, a server 100 may include a network interface 102, a processor 104, and storage 106. The storage 106 stores the software programs. The processor 104 performs operations in the server 100. The server 100 communicates with client device 110 via network interface 102 through network 122 to the network interface 118 of client device 110. The connection between the network 122 to the network interface 118 may be a wireless connection via radio access network 120 or be a hardwired connection. The network 122 may be a local area network, a wide area network, the Internet, or a combination thereof.

The client device 100 may include a variety of features including a speech interface 112, a display 114, a display interface 116, and the network interface 118. The speech interface 112 receives audio input from a user of the client device 110. The display interface 116 controls the display 114. A processor (not shown) performs operations in the client device 100.

FIGS. 2A and 2B are a signaling diagram of an exemplary procedure that includes selecting nodes and test cases for a block of source code for a program. The procedures of FIGS. 2A and 2B involve the server 100 and the client device 110. Initially, at step 200, the server 120 generates a sitemap that has a hierarchy of nodes. Each node represents a block of source code for a program. An example of a sitemap 300 is shown in FIG. 3.

The sitemap is generated by the server in one embodiment using routes. Turning to FIG. 4, for each block of source code of a plurality of blocks of source code of a program, uniform resource locators (URLs) linking the block of source code to other blocks of source code of the plurality of blocks of source code is determined at step 400. At step 402, a node is associated to block of source code to pictorially represent the block of source code. An example of a node is illustrated in FIG. 3 where nodes 304-312 each pictorially represent a block of source code. At step 404, each node representing a block of source code is linked to other nodes representing the other block of source code based on the URLs. The sitemap of the hierarchy of nodes representing the blocks of source codes is generated at step 406 based on the linking of each node to the other nodes.

Turning back to FIG. 2A, the client device 110 requests the sitemap at step 202. The server 100 transmits the sitemap to the client device 110 through the network 122 via the network interface 102. The client device 110 displays the sitemap at step 206.

In an alternate embodiment, the client device 110 creates the sitemap. Turning to FIG. 5, at step 500, the client device 110 receives, from the server 100 via the network interface 118 and network 122, information on interfaces between blocks of source code for the program. At step 502, the sitemap of the hierarchy of nodes is created based on the information received. In one embodiment, the information includes uniform resource locators. Each block of source code represented by one of the nodes in the hierarchy of nodes has a plurality of uniform resource locators (URLs) each connecting the block of source code to another block of source code represented by another one of the nodes in the hierarchy of nodes. Turning to FIG. 6, at step 600, the client device 110 links each uniform resource locator (URL) connecting a block of source represented by a node to the other blocks of source code represented by other nodes. At step 602, the sitemap is created based on the linking of the URLs. For example, the sitemap is created by linking each node to other nodes by the URLs.

At step 208, an indication of a user selection of a plurality of nodes of the hierarchy of nodes is received. The user selection may be accomplished using different techniques.

In one technique, the display 114 of the client device 110 is a touch screen display. The user selects the plurality of nodes by enclosing or partially enclosing a plurality of nodes on the touchscreen with a finger gesture. Turning to FIG. 7, at step 700, the indication of the user selection is accomplished by detecting the gesture on the touchscreen that encloses or at least partially encloses a plurality of the nodes. FIG. 3 provides an example of detecting a gesture on the touchscreen that started at some point on line 302 and finished at or near that point.

In another technique, the user selects the plurality of nodes by using a mouse to draw a line that encloses or partially encloses the plurality of nodes. Turning to FIG. 8, at step 800, the indication of the user selection is detecting a line drawn by the user via the mouse on the display that at least partially encloses the one or more nodes. FIG. 3 provides an example where a user draws line 302 on the display.

In another technique, the user indicates a path between at least two nodes on the screen by voicing the path. Turning to FIG. 9, at step 900, the speech interface 112 receives the voice selection for the user indicating a path between at least two of the nodes. The client device 110 determines which nodes are in the path at step 902.

In another technique, the user hovers a mouse icon on the display. Turning to FIG. 10, at step 1000, the indication of the user selection is detecting which plurality of nodes in the hierarchy of nodes is under a mouse icon hovering on the display.

Returning to FIG. 2A, at step 210, the lowest node in the plurality of nodes that is located at the lowest level of the hierarchy of nodes is determined. For example, FIG. 3 illustrates that nodes 304 to 312 are the plurality of nodes selected. Node 312 is the lowest node in the plurality of nodes that is located at the lowest level of the hierarchy of nodes. At step 212, the lowest level is identified as a user selected node.

At step 214, an indication of the user selected node is transmitted to the server 100. At step 216, the server 100 receives the indication. At step 218, a list of test cases for nodes in the hierarchy of nodes is determined. The test cases in the list of test cases for the nodes are the required test cases to verify the source code represented by the nodes. In one embodiment, the list of test cases was determined when the program represented by the blocks of source code was created. Turning to FIG. 11, in another embodiment, the list is determined by determining for each node in the hierarchy of nodes that requires test cases to be run when a change is made to the block of source code represented by the node, the list of test cases to be executed to the bock of source code represented by the node. The list of test cases for the user selected node is selected and transmitted to the client device at step 220. The test cases in the list of test cases for the user selected node are the required test cases for the user selected node.

In a further embodiment, the client device 110 may determine the list of test cases. Turning to FIG. 12, at step 1200, the client device 110 receives a list of program tests cases for the program. The list may be received from the server 100 or from another server or device. At step 1201, for each node in the hierarchy of nodes, the list of test cases, from the list of program test cases, to be run when a change is made to source code associated with the node in the hierarchy of nodes is determined.

Returning to FIG. 2A, at step 222, if the server 100 determines the list of test cases, the list of test cases for the user selected node are received. The list of test cases for the user selected node is displayed. Turning to FIG. 13, the list of test cases 1300 for the selected node 312 is displayed. In an embodiment, a selection of a node in the hierarchy of nodes results in the list of test cases for that node are displayed.

Returning to FIG. 2B, at step 224, an indication of a selection of a test case to be executed by the server is received. At step 226, a message is transmitted to the server 100 to execute the test case selected by the user. The server 110 executes the test case at step 228. At step 230, the results of the test case are transmitted to the client device 110. More than one test case may be selected by the user and be executed by the server. For example, a default list of test cases to be run may be received from the server. The user may select the default list of test cases to be executed by the server. Turning to FIG. 14, at step 1400, a plurality of test cases to be executed by the server is determined by receiving a user selection of a plurality of test cases or a selection of the default list of test cases received from the server. The test cases listed in the default list of test cases received from the server are the required test cases to test the user selected node. At step 1402, responsive to transmitting the message having an indication to execute the one of the test cases displayed to test the source code, the client device 110 receives from the server 100 an indication of which of the plurality of test cases that passed and/or an indication of which of the plurality of test cases that failed. Turning to FIG. 15, at the server 100, the server 100 receives a message from the client device 110 that identifies the plurality of test cases selected and that has an indication to execute the plurality of test cases. The server 100 executes the plurality of test cases responsive to receiving the message at step 1500. At step 1502, the server 100 transmits to the client device, an indication of which the test cases that passed and/or an indication of which of the plurality of test cases that failed.

Returning to FIG. 2B, at step 232, the client device 110 receives the results and displays the results. The displayed results are illustrated, for example in FIG. 16. As shown in FIG. 16, the sitemap 1600 has a plurality of nodes selected that are represented by nodes 1602-1614. The indication of which tests passed and/or which tests failed can be displayed in a variety of ways. For example, the list of test cases 1616 that were executed may have the test cases that failed being underlined, have a different color, a different shape, etc.

In one embodiment flow paths are used to also show which links to other nodes failed. A flow path is a path from one node to another node. Operations to determine which flow paths failed are illustrated, for example in FIG. 17. At step 1700, a plurality of flow paths associated with the plurality of test cases selected are determined. Each of the flow paths flows from the user selected node to another node in the hierarchy of nodes that are associated with the plurality of test cases. At step 1702, a determination of which flow paths of the plurality of flow paths has an associated test case that failed and/or which flow paths of the plurality of flow paths has an associated test case that passed. At step 1704, the sitemap is generated to show the plurality of flow paths from the node to other nodes in the hierarchy of nodes with the flow paths of the plurality of flow paths having an associated test case that failed to be displayed differently than the flow paths of the plurality of flow paths having an associated test case that passed. At step 1706, the sitemap with the plurality of flow paths is transmitted to the client device 110 for display on the display of the client device 110.

Operations to show which flow paths failed are illustrated, for example, in FIG. 18. At step 1800, the client device 110 receives and displays the sitemap having the plurality of flow paths associated with plurality of test cases. Each of the flow paths flows from the user selected node to another node in the hierarchy of nodes that are associated with the plurality of test cases. At step 1802, an indication of which of the plurality of flow paths has an associated test case that failed. The indication may be a flow path having a different color, a different shape, a different line weight, a different type of line such as a dashed line, etc. At step 1804, responsive to receiving an indication of a user selection of a flow path along one of the plurality of flow paths that has an associated test case that failed, test cases associated with the selected flow path are displayed.

FIG. 16 illustrates the flow paths associated with the test cases for the user selected node 1614. The flow paths 1618-1626 are flow paths associated with the selected test cases. Flow paths 1618-1624 are flow paths associated with test cases that passed and flow path 1626 is a flow path associated with test cases that failed. Flow path 1628 is a flow path that is not associated with the selected test cases. When a user selects flow path 1626 that failed, the list 1630 of test cases that failed are displayed. When a user selects a flow path that passed, the list of test cases for that path are displayed.

When a block of source code of a program is changed, regression testing for the block of source code is typically performed. The operations and techniques described above can be used. Operations according to further embodiments are illustrated in the flowchart of FIG. 19. As shown therein, the operations include receiving a change in source code at step 1900. At step 1902, the changed source code is stored at client device 110. The changed source code is provided to the server 100 via the network 120 at step 1904. At step 1906, a message having an indication to execute the plurality of test cases based on the changed source code is transmitted to the server 100. At step 1908, respective to transmitting, to the server, the second message having an indication to execute the plurality of test cases, the client device 110 receives, from the server 110, one of: a first indication of which test cases passed and a first indication of which test cases failed. At step 1910, the client device 110 displays on the screen, an indication of which test cases passed and/or an indication of which test cases failed.

Operations the server 110 performs when the block of source code of the program are illustrated in the flowchart of FIG. 20. At block 2000, a change in the block of source code is received. At block 2002, a message from the client device 110 having an indication to execute the plurality of test cases is received. At block 2004, the plurality of test cases is executed. At block 2006, a message is transmitted to the client device 110 having an indication of which test cases of the plurality of test cases passed and/or an indication of which test cases of the plurality of test cases failed.
